- Mayo Clinic and OrthoInfo say a common cause of knee pain on stairs is patellofemoral pain syndrome, pain around or behind the kneecap.
- Rest from repeated stair climbing, low-impact activity, strengthening and movement training with a physical therapist are the main steps.
- Mayo Clinic says supportive braces or arch supports may help reduce pain, alongside exercises.
- See a doctor if the knee will not bear weight, gives out, swells a lot, or pain does not improve in a few days.
A knee that complains on the stairs but feels fine on a flat walk is a very common problem. This guide pulls together what Mayo Clinic and the American Academy of Orthopaedic Surgeons (OrthoInfo) say about why knees hurt when climbing stairs, what helps at home, which exercises and tools are used, and when to see a doctor. We also read public patient discussions on Mayo Clinic Connect and patient-community sites to find the questions people ask most, and we answer them with the official sources. This is general information, not a diagnosis. A health care professional needs to examine your knee to know the cause.
1. Why Do My Knees Hurt When I Climb Stairs?
The most common stair-related cause named by both organizations is patellofemoral pain syndrome (PFPS), sometimes called runner's knee. Mayo Clinic describes it as pain felt in the front of the knee, around or behind the kneecap, that often increases when running, walking up or down stairs, sitting for long periods, or squatting. OrthoInfo says PFPS can occur in people who are not athletes, and that pain and stiffness can make it difficult to climb stairs, kneel down and do other everyday activities.
Mayo Clinic says PFPS usually happens when the kneecap does not move smoothly as the knee bends and straightens. OrthoInfo adds that problems with kneecap alignment, overuse, a sudden change in activity level, and weakness or imbalance in the thigh and hip muscles are common factors. Mayo Clinic also notes that PFPS typically affects teens and young adults, that females are twice as likely to develop it, and that arthritis is more often to blame for knee issues in older people.

2. Sharp Knee Pain When Climbing Stairs but Not When Walking
Stairs ask more of the knee than flat walking. Occupational therapist Julie Dorsey, quoted by the patient organization CreakyJoints, says climbing stairs sends more force through the leg than walking does. Both Mayo Clinic and OrthoInfo list stair climbing as a typical trigger for patellofemoral pain, which is why pain can show up on stairs, squats and long sitting while ordinary walking feels fine. OrthoInfo's symptom list includes pain during activities that repeatedly bend the knee, such as climbing stairs, running, jumping or squatting, pain at the front of the knee after sitting for a long time with knees bent, and popping or crackling sounds when climbing stairs or standing after prolonged sitting.
3. Knee Pain Going Up and Down Stairs With No Swelling, and Pain on the Side of the Knee
PFPS often has no obvious swelling. Mayo Clinic lists swelling, stiffness, redness, warmth, weakness or instability, popping noises and inability to fully straighten the knee as signs that sometimes accompany knee pain, and these help point toward other causes. Mayo Clinic's list of knee pain causes also includes injuries such as a torn meniscus, knee bursitis and patellar tendinitis, mechanical problems, and types of arthritis, gout and infections. Where it hurts matters, so be ready to tell your doctor whether the pain is in front, on the side or deep inside the knee, and whether you have swelling, clicking or locking.
4. How to Stop Knee Pain When Climbing Stairs: Home Care
OrthoInfo says that in many cases patellofemoral pain will improve with simple home treatment. It suggests stopping the activities that make your knee hurt until the pain goes away, changing your training routine, and switching to low-impact activities such as riding a stationary bike, using an elliptical machine or swimming. Mayo Clinic's treatment page says to rest the knee as much as possible and to try not to do things that increase the pain, such as climbing stairs repetitively, kneeling or squatting. If needed, it lists over-the-counter pain relievers such as acetaminophen, ibuprofen and naproxen sodium and says not to take them for more than 2 to 3 weeks. Icing the knee after exercise might help with pain and swelling. Check with your doctor before using any medicine.
5. Exercises and Physical Therapy for Knee Pain on Stairs
Mayo Clinic says a physical therapist might suggest rehabilitation exercises that strengthen the muscles that support the knees and keep the leg in line, with keeping the knee from moving inward while squatting as a main goal. It also lists better movement training (working on how you move, not just strength), supportive braces or arch supports that may help reduce pain, taping, icing, ready-made or custom shoe inserts (orthotics), and knee-friendly sports such as bicycling or swimming during recovery. For prevention, Mayo Clinic says strong leg and hip muscles help keep the knee balanced, especially the outer hip and core muscles, and that losing excess weight relieves stress on the knees, especially during activities that require bending the knee, such as using the stairs. Mayo Clinic says to ask a physical therapist about the exercises that are right for you. For general strength work, see our guide to resistance bands and balance exercises.
6. Should I Stop Climbing Stairs If My Knee Hurts?
Mayo Clinic advises avoiding repetitive stair climbing while the pain is flaring, and OrthoInfo says to pause the activities that hurt until the pain goes away. You do not need to avoid all movement, since low-impact activity is encouraged. If your home has stairs you must use, patient organizations suggest making them easier. CreakyJoints, a patient community, shares tips such as leading with the stronger leg going up and the other going down, using the handrail, putting your whole foot on each step and pushing off the heel, and wearing supportive shoes. These are patient-community tips, not medical orders, so ask your physical therapist what suits your knee.

7. When to See a Doctor for Knee Pain
- Mayo Clinic's PFPS page says to call your health care professional if knee pain does not improve within a few days or it gets harder to move the knee.
- Mayo Clinic's general knee pain page says to call your doctor if you cannot bear weight on the knee or it feels unstable or gives out, have marked swelling, cannot fully extend or flex the knee, see an obvious deformity, have a fever with redness, pain and swelling, or have severe knee pain after an injury.
- Mayo Clinic notes that imaging tests such as X-rays or MRI are sometimes used to find the cause of knee pain, so ask your doctor if you need them.
8. What People Ask and Say in Patient Discussions
We read public posts, including a Mayo Clinic Connect thread titled "Patellofemoral pain syndrome (PFPS) or Runner's knee" (2020), a Mayo Clinic Connect thread on stairs and knee arthritis, and the CreakyJoints article on arthritis knee pain and stairs. These are personal stories, not medical evidence, and we do not copy anyone's words or names.
- "I am 86 and I never ran. Can I still have runner's knee?" One member was diagnosed with patellofemoral disease in her 80s with no running or impact exercise. She said six months of physical therapy, home exercises and chiropractic care took the edge off, a sports medicine orthopedic doctor referred her to a therapist, and she could stand from a chair with little effort afterward. This matches OrthoInfo, which says PFPS can happen in non-athletes, and Mayo Clinic, which says physical therapy is a main treatment.
- "I have tried everything for years and it still comes in waves." A 26-year-old member said they had bilateral patellofemoral pain for about eight years. They had done hip and quad strengthening with a physical therapist, stretching, icing, a TENS unit, heat and massage, and said the biggest help was learning how to avoid pushing too hard and how to recover when they did. The official pages also say symptoms are often relieved by conservative treatment, but this person's story is a reminder that some people need long-term management and a knowledgeable therapist.
- "Going down stairs hurts more than going up." A member with severe knee arthritis said stairs are hard and that going down is harder than going up. Mayo Clinic notes arthritis is more often to blame for knee issues in older people, and OrthoInfo notes that front-of-knee pain can also be caused by patellofemoral arthritis, so tell your doctor about the pain pattern.
- "Does hurting on stairs mean I should have surgery?" Mayo Clinic says simple treatments such as rest and ice often help, and that physical therapy is the main approach for patellofemoral pain. Surgery is only considered in some cases after other treatments.
9. Knee Support and Comfort Items
These products are only for comfort and support. They do not treat the cause of knee pain, and none replaces advice from your doctor or physical therapist. Mayo Clinic says supportive braces or arch supports may help reduce pain. Make sure sleeves and braces do not feel too tight, and stop using them if you notice numbness, color changes or increased pain.
